Do you really get that much out of putting on the AIS removal kit??? I was told by the dealer you don't get that much from removing the AIS and if you leave it on it looks good when the Ranger shows up but then again I live in Calif. So far I have done most the mods such as Gray Wire. throttle stop, White Brothers E2 muffler and a RTT Stabilizer Triple Clamp. The Air box I am not sure yet the carburetor can only handle so much air I think the box is big enough to handle the air the carburetor needs????
